Results and discussion

Results:
- The pregnancy was uneventful
- The amount of amniotic fluid was normal during pregnancy, but reduced at term
- In week 39 of gestation, the woman delivered a girl with left-sided facial palsy and plexus paresis, but otherwise seemingly healthy.
- At age 24 h the child was still anuric and serum creatinine was 389 mol/L.
- At day 5, Creatinine rose to a maximum of 530 mol/L; at the same time production of urine started (fraction excretion of sodium 12%), and became normal 6 days later.
- From day 6 to day 28, substitution with sodium hydrochloride and potassium hydrochloride (2 mmol/kg daily of each) was necessary.
- At age 1 month, creatinine had dropped to normal values (27 mol/L).
- Sonography initially showed hyperechogenic kidneys with poor corticomedullary differentiation. The sonographic appearance of the kidneys normalised during the following month.
Plasma renin activity (53·0 ng/mL every hour) and aldosterone (12·6 nmol/L) were very high at day 8. Renin activity was still high at day 35 (52·0 ng/mL
every hour).
- At age 8 months, the girl had developed normally. Plasma renin activity and aldosterone had returned to normal values (3·4 ng/mL every hour and 14
nmol/L, respectively). Only a discrete facial and plexus palsy remained.

Applicant's summary and conclusion

Conclusions:
This case is highly suspicious for acute perinatal prerenal failure induced by the angiotensin-II-receptor inhibitor and postnatal hypovolaemia
